CONTROL DEVICE, POWER SUPPLY CONTROL DEVICE, CHARGE CONTROL METHOD, CHARGE CONTROL DEVICE, AND POWER SUPPLY DEVICE FOR VEHICLE

A control apparatus that is capable of quickly charging a storage battery and allowing the storage battery to store a large amount of electric power is provided. A control apparatus 1 controls charging from a power generator 22 to a storage battery 23. A switch 10 is provided on a first charge channel via which the power generator 22 charges the storage battery 23, and a DCDC converter 11 is provided on a second charge channel via which the power generator 22 charges the storage battery 23. The DCDC converter 11 steps up a voltage generated by the power generator 22, and applies the stepped-up voltage to the storage battery 23 via an electric wire 21. A control unit 14 controls the switch 10 and the DCDC converter 11 such that, when a charge current value detected by an electric current detection unit 12 becomes smaller than a predetermined value under a condition where the storage battery 23 is being charged via the first charge channel, charging to the storage battery 23 is switched to charging via the second charge channel.
